GUARD OR PROTECTOR FOR LOCOMOTIVE-CABS; &c.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed September 25, 1908. Serial No. 464,672.

To all whom it may concern:

A represents the engineers cab of a low- Be it known that I, THOMAS J. Quinn, a motive which is usually provided on one side citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful linprovement in Guards or Protectors for Locomotive-Cabs, &c., of which the 'l'ollowing is a specification.

This invention relates to a stonn guardor protector which is more particularly dcsigned'for use on locomotive cabs or street car vestibules but which may also be used on I buildings, the pilot houses of boats and else- Where. Heretofore such cabs and vestibulos rovided with a window having a lower fixe sash and an upper movable sash which was opened in pleasant weather and closed in stormy or unpleasant weather. The closing olv both. sash while it is rainin snowing or while insects are numerousin t e air is objectionable, because the lass becomes covered with water, snow or insects and thus interferes with the engineers, motormans or pilots view of the road ahead. Furthermore, the rellection ol' the light of the cab lam ou.the closed window panes interferes wit 1 .the View through the same.

One of the objects of this invention is to provide a guard or )rotcctor of the character described which will permit ol' leaving part of the observation window open at all times and thus do away with the objection of the glass becoming covered with snow, rain or insects, but at the same time preventing the objectionable matter from entering the com nn'tmerit while the window is thus opened, there- 1) ermitting a person to have a clear View ol the track ahead.

- Another object ofthis invention is to cause a circulation of air on the inside of the movable sash of the observation window when the same must be closed in case the guard or n'event condensation on this sash which otherwise would obscure the view of the watchman.

' In the accompanying drawings: Figure l 1 is a longitudinal sectional elevation of a loco- -mot-ive cab having its forward or observation Window provided with my guard or protoctor, showing the parts 111 one po ition. Fig.

2 is a similar View showing t e parts in another position. Fig. 3 is a fragmentary imntelevation of the same. 1

Similar letters of reference indicate corresponding parts throughout the several views.

l I l slide through a brac of its front wall with a door B the upper part of which contains a lower fixed window sash C and an upper movable window sash D.

,T he latter is pivoted at its upper end on the door frame so that it can be swung forwardly and upwardly into its horizontal open position or downwardly and rearwardly into its vertical closed )osition. Theupperwindowsash maybe held in difl'orent positions by any suitable adjusting device that shown in the drawings being in common use and consisting of a curved rod E secured at one end to the up per sash while its op osite end is adapted to lzet e on the door B and be held therein by a set screw f.

in the closed position of the upper sash the lower edge thereof overhangs or overlap the upper edge of the lower or fixed sash of the window but a vertical passage .9 between the meeting parts of these sashes is formed to permit external air to enter the cab and sweep upwardly across the inner side of the u iper sash. By' this means condensation on tic inner side of the up or sash is avoided and n'cventcd from inter ering with the'view of t 1e engineer through this window sash.

T his is particularly desirable when the upper window sash has to be closed in case the guard or protector is broken. The preferred way of producing this air assage consists in constructing the lower 'ed window sash without an upper horizontal cross bar, or rail, so that a space is left between the upper edge of the glass ane of the lower sash and the lower bar h ot the upper sash, as shown in the drawings. I

flhe guard or protector has a hood or case which comn'ises two upright side walls I, I extending l'orwardly from the cab door on opposite sides of the upper and lower sashes o the observation window and a transverse horizontal roof or top J extending forwardly from the door above the up or sash and connecting the upper ends of t e side walls I, I. Betwocnthe lower front parts of the side walls and secured at opposite vertical edges thereto is an upright transverse wind break which is so arated from the op osing lower sash of the o servation window y an intervening vertical pass e k which'is open at the top and bottom. he wind break ispreferablly constructed the form of a window sash 'aving a glass or transparent pane which permits the engineer to look downwardly .et

an angle through the panes of the lower sash of'the observation window and the wind break and view the track immediately in front of the locomotive. The wind break preferably inclines from its upper end toward lts lower end so that any rain, snow or insects striking the front side of the same will be deflected, downwardly, thereby reducing the tendency to lodge on the wind break and interfering with a clear view through the same.

Above the windbreak is a deflector L..of metal or other opaque material 'which is secured to the front edge of the top of the easing and separated from the upper edge of the clines from its upper edge toward its lower edge, whereby snow and rain in stormy weather striking the deflector will be directed downwardly into the passage between the ,wind break and the lower sash of the observati'on windowand escape from the lower end of this passage. The deflector is able to thus' direct the material downwardly through the assagelc inasmuch as the .bod of air 1n the atter is quiet and not under orizontal pressure on account of the wind break K which prevents the air from pressing horizontally against the lower sash. O of. the

' observation window. By this means the snow and rain and also insects are prevented from enteringthe cab through the observation window if the upper sash is open, which otherwise would'interfere with the engineer obtaining a clear view of the road ahead.

The downward current of air in the passage which is produced by the deflector also prevents accumulation of rain, snow and in-- sects on the outer side of the lower observa tion WlIldOW sash and prevents condensation on the inner side of the glass of the wind break, so that the engineer can always look through the same.

My improved guard or protectornot only, 5 revents rain, snow and insects from enterln through the observation window of the ca when thesame is open,.but also prevents any interference with the'view of the engineer from the light of the cab lamp, inasmuch as the guard .or protector avoids the necessity of closing the upper sash of the observation window and thus eliminates the reflection of the cab light on the glass pane of the cab window which otherwise would occur and obscure the view of the engineer.
